multiple-PWM on g2553 (based on slaa513) does not seem to work

Hi,

I'm having problems with multiple-PWM signals on my G2553, to be more specific, only with timer A1 and TA1CCR2.

The entire thing is based on slaa513 and i don't see the point where i'm making a mistake.

I'm looking at it for a few days now and i don't get it to work by trying different things in the code.

The behaviour that i see is that i get interrupts on Timer A1, also i get them for TA1CCR2 (TA1IV -> case 2), but it does not detect if the pin is high (TA1CCTL2 & CCI ).

When looking at the pin with a scope, i'll see that the pin is high and low, 60us high and 60us low (so a duty-cycle of 50%).

So it looks like that (TA1CCTL2 & CCI) is always false, so the code "TA1CCR2 += 160;" is never executed (also placed breakpoints here, never executed).

Fot the other counters TA1CCR0 and TA1CCR1 it is working as expected, the code is very simular.

Below the simplified code i'm using, which still contains the weird behavior.

Also disabled the other counters and the problem is persitent.

Any help is appeciated.
